I'm not bashing on him in any way. Props to him for building a really nice conversion. I read the post more as academic (hence, "how could he have done better?") Maybe there's more that could be read into that...I haven't been following whatever other disagreements have been going on about LiFePO4, BMS, or whatever.

I see my bike pop up on other forums and such, I read people's comments and learn from them (or I just ignore them). Emailing him directly would be a nice gesture though.

His page says it was last updated 2/16/10. I'm pretty sure he could have put 2000 miles on his bike in two years. As for cost, all the little things add up. Also, he may have had labor costs to machine or design.

I think my 24 Hi Power lasted about 50 charges before they started to stop cooperating with each other. It might have been the BMS, or asking 3C from them, or just the chemistry of the various cells giving up the ghost at different rates. I don't think those Chinese LiFePo4 batteries were really designed for the abuse that they got.
